Name: ME231C Engineering Thermodynamics I ? Quiz 1 Time: 20 minutes Number of Questions: Three Number in the parenthesis after the question number indicates full marks. Closed book and closed notes. One sheet of notes on 8.5? x 11? paper is allowed. Write relevant equations before plugging in numbers. It will give you partial credit in case your numerical answer is not correct. Underline or circle your answer. Always write units. Question # 1 (10): Gravity decreases with altitude, since greater altitude means greater distance from the Earth's centre. If someone climbs to the top of Mt. Everest, he/she will be about 5.5 mile above sea level where the acceleration of gravity is 32.09 ft/s2. If a person whose weight is 200 lbf in Ames where acceleration of gravity is 32.2 ft/s2 climbs to the top of Mt. Everest, what would be his weight? What is the mass of the person? Neglect all other variations. Question # 2 (6): During a process, the temperature of a system rises by 100°C. What would be the rise in temperature in K °F °R Question # 3 (10): Air contained within a piston-cylinder assembly is slowly heated. As shown in Figure, during this process the pressure first varies linearly with volume and then remains constant. Determine the total work, in kJ. State Volume, m3 Pressure, kPa 1 1 50 2 3 100 3 5 100 ME231C Quiz 1
